Size of the glow to be rendered for visibility testing. Must be larger than the distance from the sprite center to empty space. So if this glow is inside geometry (like a light bulb), set this value to be bigger than the bulb's radius. Any time a sphere of this radius would be visible (poking through any nearby geometry), the glow will be rendered.

Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior.

Note:Try to avoid expensive operations in this function, as it may cause performance problems.

Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.

Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.Format: <key> <value>Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>

Execute a string of script source code. String quotation may be needed when fired via console.

Note:The code is executed in the script scope of the entity that fires the output, not the one of the targeted entity.

Warning:Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.
